Case Discussion

This finding demonstrates typical features of a hydrocele of the canal of Nuck. It is a rare condition in females, caused by a failure of complete obliteration of the canal of Nuck. The canal of Nuck is an abnormal patent pouch of peritoneum extending anterior to the round ligament of the uterus into the labia majora.

The main differential diagnosis is a inguinal hernia, but in this case you don't see a herniated bowel loop or another organs in this area.
